标签： maven jsf tomcat facesservlet classformaterror

我想在Tomcat 7中使用Mojarra 2.1， 所以我在我的pom文件中添加了以下依赖项：

<dependency>
       <groupId>com.sun.faces</groupId>
       <artifactId>jsf-api</artifactId>
       <version>2.1.2</version>
     </dependency>

     <dependency>
       <groupId>com.sun.faces</groupId>
       <artifactId>jsf-impl</artifactId>
       <version>2.1.2</version>
     </dependency>

但是，当我尝试启动Tomcat时，我遇到了以下异常：

这是如何引起的？如何解决？

这是我的web.xml文件，其中可能包含问题原因：

我遇到与您相同的问题，并发现从servlet-api更改为javax.servlet.api可以解决问题。希望这有帮助。请注意，我使用的是Juno Eclipse，Tomcat 7，Dynamic Web Module 3.0和JDK 1.7。

<dependency>
  <groupId>com.sun.faces</groupId>
  <artifactId>jsf-api</artifactId>
  <version>2.1.13</version>
</dependency>
<dependency>
  <groupId>com.sun.faces</groupId>
  <artifactId>jsf-impl</artifactId>
  <version>2.1.13</version>
</dependency>
<dependency>
  <groupId>javax.servlet</groupId>
  <artifactId>javax.servlet-api</artifactId>
  <version>3.0.1</version>
</dependency>

答案 1 :(得分：8)

我遇到了同样的问题，它以某种方式接缝

<groupId>javax</groupId>
<artifactId>javaee-web-api</artifactId>

或

<groupId>javax</groupId>
<artifactId>javaee-api</artifactId>

将它们设置为范围提供（或在maven测试中启动服务器时完全删除它）它开始为我工作。

@查看此博客：j ava.lang.ClassFormatError : Absent Code attribute in method that is not native or abstract in class file … - 它讨论了javax.persistence.GenerationType的问题，但我认为你和我遇到了同样的问题。

变化：

<dependency>
   <groupId>com.sun.faces</groupId>
   <artifactId>jsf-impl</artifactId>
   <version>2.1.2</version>
 </dependency>

要：

 <dependency>
    <groupId>org.glassfish</groupId>
    <artifactId>javax.faces</artifactId>
    <version>2.1.6</version>
 </dependency>

答案 4 :(得分：3)

我交易到glassfish-embedded-all并解决了这个问题。

    <dependency>
        <groupId>org.glassfish.main.extras</groupId>
        <artifactId>glassfish-embedded-all</artifactId>
        <version>3.1.2.2</version>
